Gun control advocates are calling on major U.S. gun retailers to voluntarily follow a background check process on gun sales they say could prevent tragedies such as the Charleston Church Shootings.  Cabellas, EZPawn and Bass Pro Shops are being urged to follow Wal-Mart's lead and refuse to sell a gun to anyone until a background check is complete.  

5th District Congresswoman Elizabeth Esty says a federal law loophole allows a sale to proceed if a check is not completed in three days.  Even though the Charleston shooter had a criminal record that should have been flagged, the sale was allowed to go through because of the three day rule.

Connecticut already requires a completed background check, no 3 day time limit.
